Are these eggs?

Was doing some cleaning today and noticed what I thought at first was bubbles. When I brushed up against it slightly they didn't move though. Would be the weirdest bubbles I've seen lol.
This is on the return tube right where our bonded clown pairs hang out basically 24/7.

Bubbles

I kinda figured but had someone think they could be eggs. Was just weird to me that when I brushed the return, they didn't move. And how securely they were attached to the pipe too. I would say the female clown got real ticked when I got close to them but she's always mean lol.

All the bubbles are still in the exact same spot and nowhere else in the tank lol.
